Vietnamese Turmeric Fish with Wilted Herbs and Peanuts

This dish draws inspiration from a Hanoi restaurant, Cha Ca La Vong, renowned for its fish—the only item on the menu— seasoned with turmeric and dill. For our version, cornstarch and ground turmeric form a delicate crust on tilapia fillets that are quickly sautéed. Other firm white fish, such as snapper or cod, would work well here, but you'll need to increase the cooking time for fillets thicker than ½ inch. Generous fresh herbs—we use scallions, dill and cilantro, but mint is great, too—along with a sauce of lime juice and fish sauce brighten the dish. To add spice, stir red pepper flakes into the sauce or offer Sriracha at the table. Serve with thin rice noodles.
